Worked on enhancing the nuxt/nuxt repository by implementing SHA256-based hashing for prerender cache keys, focusing on improving security and reliability in the caching process. Utilized JavaScript and Node.js to update the normalizeFsKey function, ensuring that each cache key is generated with a SHA256 hash of the input item. This approach reduced the risk of cache key collisions and strengthened the integrity of prerendered content, leading to more consistent and predictable build outputs. The work demonstrated a strong understanding of caching strategies and security best practices, addressing potential vulnerabilities in the prerendering workflow without introducing new bugs.
